CANNON Instrument Company® | Operation 38


Operation The CAV 4.2 can be operated in either local or remote mode through a pair of software programs. In Local Mode, the CAV 4.2 GUI (graphical user interface) software program controls the instrument, while in Remote Mode a separate computer with the VISCPRO II software program installed controls it. Each of these programs is independent of the other and maintains its own data set, where a data set consists of a run of tests, test results and error logs. Common instrument settings, method templates, and equipment status are shared between the programs.

The operating status of the CAV 4.2 is shown on the left-most button of the main screen menu of the CAV 4.2 GUI. This button toggles between Local Mode and Remote Mode. A green icon indicates that the instrument is connected to VISCPRO II. In Remote Mode, the Users, Results, and Errors action buttons are grayed to indicate that instrument operation cannot be managed from the CAV 4.2 GUI.

Calibrate Viscometer Tube (VISCPRO II) Viscometer tube calibration values are associated with specific temperatures, so calibration must be performed when operating a CAV 4.2 bath at a new temperature. Once a tube is calibrated at a particular temperature, the C and E constants are saved by the instrument and will be recalled if that tube is set to run at that temperature again.

1. Assemble a set of standard oils with known kinematic viscosities. Use at least different two standards for each bulb to be calibrated. The CAV 4.2 is designed to run "thin" standards (those with viscosities less than 10X the lower limit of the viscometer tube) in two bulbs, while "thick" standards (those with viscosities greater than 10x the lower limit of the viscometer tube) run in only the lower bulb.

2. Follow the procedures in Run a sample test to prepare, load, and run all of the calibration standards as method Verify Known KV.

3. When all tests have completed, from the VISCPRO II Menu, select Configure > [instrument group] > [instrument] > Tube Calibration. The Tube Calibration window opens.

4. Select the tube and the bulb to calibrate.

5. Select the date range from which to retrieve appropriate test data.

6. Select the sample entries to use for calibration. You must select at least two entries or the software will not recalculate the constants.

• Shift-left-click—to select a contiguous range of entries.

• Ctrl-left-click—to select multiple entries.

7. Click Calculate new constants. The new C and E constants display in their respective fields.

• Evaluate the accuracy of the new calibration constants for each standard by comparing the Known Viscosity with the Calculated Viscosity. This difference is displayed as a percentage


in the % Difference column. You can repeat the calibration by selecting other sample entries.

• Check Limit E Constant before calculating constants to limit the E constant to no more than 10000.

8. When the new calibration constants are acceptable, click Update bulb to save the C and E constants and calibration data to the local database and update the C & E constants in the registry of the CAV 4.2.

Method/Test Settings Method templates are stored in the registry of the CAV 4.2. When an instance of VISCPRO II connects with a CAV 4.2, those method templates are pushed to VISCPRO II. Any changes made to the method templates in VISCPRO II are synchronized with the CAV 4.2. No method templates are permanently stored with VISCPRO II.

All method templates have the same set of fields. However, when the Verify Known KV method is applied to a sample test, the Check Standard KV value is added to the information set for that test. The Verify Known KV method must be used when running sample test for calibration.

Change Viscometer Tube

Warning: Do not drain the silicone bath fluid until it has cooled off to a safe temperature.

1. Turn off the CAV 4.2 and allow the bath to cool down.

2. Drain the silicone bath fluid into a clean container and save for refilling the unit.

3. Raise the hood.

4. Note the solvent line connections. Gently unscrew the solvent lines from the top of the viscometer tube.

5. Disconnect the sensor cable by gently pulling straight up.

6. Unscrew the thumb screws until they spring free of the bath top.

7. Gently draw the viscometer tube straight up and out of the bath.

8. Inspect the new viscometer tube for defects, especially small chips on the top and bottom of the tube. These can cause vacuum leaks and problems with solvent contamination.

9. Clean the bottom of the new tube and apply a light coating of silicone bath fluid.

10. Gently lower the viscometer tube into the bath and press it into the cone of the tube tip in the bottom of the bath. The viscometer tube must pass through 2 o-rings in the cone and seat gently onto the top of the metal tube tip. Failure to seat the viscometer tube properly may result in poor performance.

11. Press the top bracket into position and evenly tighten the thumb screws.

12. Verify that the bath drain set screw is tight and refill the bath with silicone bath fluid.

13. Connect the solvent lines and sensor cable.

14. Turn the CAV 4.2 on.

15. In Tube Settings, enter the name of the new tube.

16. If necessary, adjust and calibrate the temperature of the bath. If the temperature has not changed, temperature calibration is not necessary.


Note: Sensor training data is associated with the temperature setting of a bath. When a tube is changed and the bath temperature is either kept the same or changed to a temperature at which a tube was previously trained, the CAV will display that the sensors are trained. This is correct. The sensors must be trained whenever a tube is changed.

17. Train the sensors.

18. Verify the Default Wash and Method Settings, especially Verify Known KV, for the bath in which the tube was changed.

19. Calibrate the new viscometer tube.

Replace Power Supply The CAV 4.2 power supply is a switching regulated power supply designed to handle 90 – 240 VAC. To accommodate different locales, only the MAINS AC power cable needs to be changed.

Caution: The power supply is easy to replace. The side panels do not need to be removed to access the power supply attachment point. It is not connected via cable. Instead, a mating coupler is attached to a bulkhead in the chassis.

1. Turn off the CAV 4.2 and unplug it from the MAINS AC power.

2. Remove the power cable.

3. Remove the four screws securing the power supply assembly to the chassis.

4. Firmly pull the power supply assembly from the chassis.


Adjust Solvent Dosing Chamber Sensors Each CAV 4.2 bath has its own solvent dosing chamber, mounted on the side panel. Optical sensors on the inlet and the outlet of the dosing chasing must be adjusted to "see" the solvents that are drawn past them.

When the chamber is full of solvent, adjust the sensors by turning the set screws counter-clockwise until the associated green light turns on. When running multiple solvents, verify each solvent, always adjusting by turning the screws counter-clockwise.
